HI Don - what he meant is that a regular eGo without the 3.2v regulation, under load, was going a bit lower than the eGo Variable that we sell which in various tests comes in around the 3.9 mark or so.
What this promises you basically is a high, medium and low power setting...with no load that has been measured at 3.2/3.7/4.2. With a load and depending on the discharge of the battery, that varies. The manufacturer comments a low, medium and high
vaping experience (they don't actually give numbers, they just say "low, medium, high") in their manual (which for the Chinese, its written in really good English by the way).
